Product: Resin Trap
Country: Vietnam
Application: Resin
The resin trap is a device used to trap resin particles that are carried out of the ion exchanger with the water.
When using resin for water treatment, when the resin is damaged for various reasons, the resin will enter the entire water system and affect the normal operation of other equipment in the system, so it is necessary to install a resin trap. The resin trap is mainly to install a filter screen with a much smaller pore size than the resin on the water system pipeline near the outlet of the resin-filled equipment such as the ion exchanger. When the resin passes through, it can be intercepted and captured by the filter screen, and the captured resin Drain out of the system.
The reasons for resin breakage are as follows:
1. Poor manufacturing quality. During the resin manufacturing process, due to improper maintenance of process parameters, some or a large number of resin particles will be cracked or broken, which is manifested as low crushing strength of resin particles and low sphericity after grinding.
2. Freeze. Resin particles contain a large amount of moisture. When stored or transported at sub-zero temperatures, this moisture will freeze and expand in volume, causing the resin particles to crack. Frozen resin shows a lot of cracks under the microscope, and serious breakage occurs in a short period of time after use. In order to prevent the resin from freezing, the resin should be stored at 5-40°C and avoid transportation during the freezing period.
3. Dry. When the resin particles are exposed to the air, they will gradually lose their internal moisture, and the resin particles shrink and become smaller. When dry resin is immersed in water, it rapidly absorbs water and expands the particle size, causing cracking and chipping of the resin. For this reason, the resin should be kept sealed to prevent drying out during storage and transportation of the resin. For the resin that has been air-dried, it should be immersed in saturated salt water first, and the high concentration of ions in the solution should be used to suppress the expansion of the resin particles, and then gradually diluted with water to reduce the cracking and breaking of the resin.
4. The effect of osmotic pressure. Resin under normal operating conditions, during the failure process, the resin particles will generate internal stress of expansion or contraction. In the long-term use of the resin, the repeated expansion and contraction of the resin is the main reason for the crack or breakage of the resin particles. The rate of resin expansion and contraction depends on the rate of resin transformation, which in turn depends on the salt concentration and flow rate of the incoming water. When gel-type resin is used for chemical desalination of natural water, the maximum flow rate generally does not exceed 40m/h, and when used for demineralization of condensate water, the maximum flow rate generally does not exceed 60m/h. The macroporous resin can withstand a large transformation speed due to its firm skeleton structure and large porosity, and the flow rate of condensed water can be as high as 100m/h.

Resin traps are divided into Y-type resin traps, tubular resin traps, and vertical resin traps.
1. The inside of the Y-type is a single stainless steel wire-wound filter element type, with an O-ring sealing ring, and the equipment is lined with 1751 semi-hard rubber.
2. The inside of the tube is a single stainless steel wire-wound filter element, which can be used for make-up water and low-pressure condensate water systems. Equipment lined with 1751 semi-hard rubber.
3. The vertical internal device is in the form of multiple stainless steel wire filter elements, and the internal anti-corrosion of the equipment adopts black epoxy asphalt paint. Generally used for large units.
